Interactive Fiction (n): (1) A somewhat pretentious term for text adventure games, originally used by Infocom about their products, nowadays mostly in use among the self-appointed elite of, to give a (presumably) more high-brow flavour to text based games, as opposed to the graphic ones preferred by basically everybody else. This usage is constantly confused with

(2) Any kind of written fiction with interactive elements, usually used about hypertext documents where the reader can select different storylines by choosing different links. The devotees of Interactive Fiction in this second sense tend to be puzzled by sense (1), considering the application of the term "fiction" to mere games a contradiction in terms.
